I have made a lot of changes to my flutter app including updating packages to their latest/resolvable versions.
NOTE: My app builds perfectly fine in VScode when I run the app in debug and if I use flutter run. No problems there.
So, now it's time to archive and send my build to the Apple. I would normally do this by opening up Xcode, archiving my latest build and then using Xcode Organiser to Distribute App.
Problem is, the build fails in Xcode before it can archive. I get these errors in Xcode:

I've tried, flutter clean, flutter pub get, deleting /ios/Pods and /ios/podfile.lock. Running pod deintegrate and pod install --repo-update from the /ios directory. I've tried running rm -rf ~/.pub-cache/hosted/pub.dartlang.org/
WHAT I TRIED (that you probably won't need to do):
I initially created a new flutter project with the same name. Then copy-pasted all my lib files over to the new project shell. Updated the config files where necessary. I still had the same issue!
HOW I SOLVED IT:
Turns out it was just an issue with an outdated package.
In my case, this package, flutter_native_timezone, had stopped being updated and I found a package that was being updated (that was a fork from the outdated one). flutter_timezone.
Note that I also made an effort to remove all unused packages and get all packages to their actual latest versions.
